The complete truck range of Toyota has been designed to work effectively down to 0°C without modification. However, for temperatures down to -30°C most trucks will need to be adapted. Specific features can include stainless steel, cold store oil, anti-slip platforms, heated batteries, etc. Toyota offers a range of warehouse trucks including hand pallet trucks, order pickers, reach and Very-Narrow-Aisle trucks (VNA), as well as counterbalanced trucks that can be fully engineered for cold store use. Some trucks require little modification, for example, Toyota BT Levio pallet trucks and BT Staxio stacker trucks simply need low-temperature hydraulic oil – in all other respects they are pre-engineered for cold stores with fully sealed components. All cold store machines are clearly defined by the snowflake symbol. This helps drive down costs by reducing the risk of trucks being incorrectly used.
